Title: Method and apparatus for making a metal blank of rectangular shape
IPC: B21K1/64
Filed: 1959-02-20
Abstract: 872,016. Forging; making coils for dynamo-electric machines. TEXTRON Inc. Feb. 20, 1959 [Feb. 27, 1958], No. 5885/59. Classes 83 (2) and 83 (4). A rectangular section blank, Fig. 5, particularly for an electric motor coil, is made by upsetting a substantially circular workpiece. Circular rod stock 14 fed through a die 12, Fig. 1, is severed by a knife 15 and transferred thereby to station 1 where it is sized and chamfered in a die 16 by a punch 18 carried by a reciprocating gate 11. The blank is transferred by gripping fingers, during which it is turned end-to-end, to Station 2 where it is upset by a punch 29 in a die 24 having an elongated opening 25 with flat sides 26, Fig. 2; this forms the blank of Fig. 10 (not shown). At Station 3 it is further upset in die 35 by punch 36 into substantially solid rectangular shape, Fig. 12 (not shown), and at Station 4 it is upset to true rectangular shape in a die 45 between a sleeve 46 and punch 49. A pin 47 and a projection 50 on the punch indent both,faces of the blank, Fig. 12 (not shown). At Station 5 the blank 59 is pierced by a punch 57 and subsequently removed therefrom by a stripper 61. Knockout pins 20, 28, 38, 47 are provided at Stations 1-4: respectively. The rectangular openings in dies 24, 37 are disposed obliquely to facilitate gripping of the blanks by the transfer fingers upon ejection from the dies.

Abstract: 1,089,840. Sewing machines. UNION SPECIAL MACHINE CO. Feb. 11, 1965 [March 23, 1964; April 20, 1964], No. 5920/65. Heading D1G. A machine for seaming together the edges of fabric having varying shapes comprises a sewing head 31 mounted on a platform 30 pivoted at P1 to a frame 23 slidable on rails 24 carried on a fixed frame 22, a table 1, and a conveyor 2 for feeding workpieces along to presser foot 35 and the needle. The piston rod 56 of a hydraulic jack 57 is coupled at P2 to platform 30 for moving the machine along rails 24 whilst the piston rod 60 of a jack 61 is coupled at P3 to platform 30 for turning it about pivot P1 against springs 63. As the work is fed by conveyor 2 the contoured edge thereof passes over a light source 44a for a photo-electric cell 44 controlling the jacks 57 and 61 to traverse or pivot the sewing machine to follow the contoured edge of the work. A photo-cell 10 receiving light from a source 12 serves to start and stop the machine. A photo-cell 39 receiving light from a source 41 serves to energise a solenoid to raise the presser foot through a linkage 38 to admit the work thereunder. A photo-cell 42 receiving light from a source 45 serves when actuated to repress the action of photo-cell 44 so that a straight seam is sewn. Photo-cells 50 receive light from sources 52 and serve to energise a solenoid for actuating a thread chain cutter 4 through a linkage 49. Cutter 4 operates when the leading photo-cell 50 is obscured for cutting the thread chain at the leading edge of a workpiece and operates again when both photo-cells 50 are illuminated for cutting the thread chain at the trailing edge of the work. A photo-cell 17 receiving light from a source 19 senses to actuate a stocker as described in Specification 1,048,646. It is stated than air jets may be used for the fabric edge detection instead of photo-cells and that the serving machine may remain stationary while the fabric is moved in accordance with the edge contour.

Abstract: 931,029. Automatic exchange systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Feb. 14, 1962 [Feb. 23, 1961], No. 6691/61. Class 40 (4) In a multi-stage relay cross-point system in which the cross-point contact sets are controlled by more than one relay one of which acts as a control relay, the operating coils of the relays and the contact set of the control relay are connected in series between the control conductors of the horizontal and vertical multiples defining the cross-point, and a marking connection including a rectifier is connected between the coil of the control relay and its contact set, it being arranged that when a path is being set up between a number of stages all the control relays are nearer one end of the control connection than their corresponding contact sets. The system is very similar to that described in Specification 917,017 and differs only in that a plurality of relays is used at each cross-point. The construction of the relays which are of the reed type is mentioned with reference to Fig. 3 (not shown) but is described fully in Specification 931,028. As shown in Fig. 2 when a subscriber wishes to make a call, a transmission bridge XB is allocated to the call and a control circuit CONT serves to mark a path between LC and XB. A contact MXB in the control circuit closes so as to apply positive potential over marking connection om to the vertical multiple VB (Fig. 1), to which this bridge pertains. Thereafter a switch MB is operated to apply earth marking over mb to a particular horizontal multiple in each of the arrays B1-Bn so that relays RB1, RB2 operate. Switch MA then operates and MB releases, the former extending earth marking over connection ma to a particular vertical multiple in arrays A1 to An so that relays RA2, RA1, RB4, RB3 now come up in series with RB2 and RB1. Finally RA4, RA3 energize in series with the control connection already set-up and contact k in the transmission bridge operates to apply holding earth to the connection, the control circuit releasing on relapse of MA and MXB. Other configurations of relays RA1- RA4 and RB1-RB4 are discussed with reference to Figs. 4a and 4b (not shown).
